Comb

ABSTRACT

The purpose is to reduce a load on fingers which grip a comb and to increase a gripping power to the fingers which grip the comb. In a comb, first and second recessed parts of a curved shape are formed in both perimeter edges of edge comb parts in width directions, respectively, and also first and second comb tooth recessed parts of a curved shape are formed in both perimeter edges of a plurality of comb teeth in width directions. When one of the edge comb parts is mainly gripped by the fingers, the fingers are fitted into the first or second recessed part of the edge comb parts and also into the first or second comb tooth recessed parts of the comb teeth located nearby. Since each of the recessed parts has the curved shape, it achieves surface contact with the fingers.

TECHNICAL FIELD

The present disclosure relates to a comb which is made easily gripped and makes it difficult for a hair bundle scooped up in a hairdressing task, etc. to slide down, by forming a curved depression in an edge comb part or comb teeth provided to a comb main body.

BACKGROUND ART

Conventionally, combs used for hairdressing, etc. commonly have a structure in which an edge comb part is protruded from both ends of a bar-shaped comb main body, respectively (one-end edge comb part provided to one end side in the longitudinal directions of the comb main body, and the other-end edge comb part provided to the other end side), and a plurality of comb teeth are provided between the edge comb parts provided to both of the ends.

The following Patent Document 1 illustrates one example of the conventional comb, where the shape of a comb tooth in a state in which the width directions of the comb tooth are oriented to the front has a tapered wedge shape, and the perimeter edges on both sides (perimeter edges illustrated by the vertical lines on the both sides) are formed by the straight oblique lines (see FIG. 2 of Patent Document 1), and the shape of the edge comb part in a state in which the width directions of the comb edge part are oriented to the front has also a tapered shape, and the perimeter edges on both sides are formed by straight oblique lines (see FIG. 17(B) of Patent Document 1). In addition, this Patent Document 1 also illustrates the edge comb parts having through-holes which penetrate in the width directions thereof (corresponding to a tip-end part 2a or a base-end part 2b of Patent Document 1; (see FIGS. 1, 5, 6, etc. of Patent Document 1). Note that, generally, types of the shape of combs can be roughly classified into a type having a grip part (tail part; e.g., the type illustrated in FIGS. 7, 8, 10, 11, 13, 14, 17, 18, etc. of Patent Document 1) and a type which does not have the grip part (e.g., the type illustrated in FIGS. 1, 5, 15, etc. of Patent Document 1).

Moreover, the following Patent Document 2 discloses one in which a notched part (6) or a central recessed part (7) is formed in a perimeter edge on one side in width directions (front side of the comb) of comb teeth (see FIGS. 1 to 4 of Patent Document 2). Similarly, the following Patent Document 3 also discloses a comb in which a groove 3b which is notched in a corrugated and arc shape is formed in perimeter edges (outside surface) on one side (front side of the comb) or both sides (front side and back side of the comb) in width directions of comb teeth (see FIGS. 7 and 8, and Par. [0016] of Patent Document 3). Further, the following Patent Document 4 discloses a comb in which a notched part 34 is formed in a perimeter edge on one side in width directions is formed in comb teeth provided to a cap with the comb (see FIG. 7 and Par. [0005] of Patent Document 4).

Note that the following Patent Document 4 discloses a ring comb for permanents which is provided with curved and inclined comb teeth. Moreover, the following Patent Document 5 discloses a brush for hair coloring in which depressed parts (finger holding parts) sized to hold a finger are formed in a side surface of a brush base part in order for the comb to fit in a hand and in order to make it difficult for the comb to slip.

DESCRIPTION OF THE DISCLOSURE Problems to be Solved by the Disclosure

Beauticians and barbers who are professional users of combs change the method of holding the comb in various ways according to the type of task. An example of a method of holding the comb is holding the comb so that while fingers contact comb teeth, one finger (e.g., a thumb) contacts both an edge comb part and comb teeth located in a range near the edge comb part, etc. However, if such a holding method is adopted, since the comb teeth and the edge comb part have the perimeter edge of a straight (linear) shape as described above, and on the other hand, the part of the user's finger(s) which touches the comb side has a curved shape in the holding method described above, the contacting state between the comb side and the user's finger(s) side becomes a point contact.

The beauticians and barbers who are professional comb users may perform the task using the comb while water, hairdressing fluid, etc. is adhered to the fingers, and when water, hairdressing fluid, etc. is adhered to the fingers, the finger surface becomes slippery. If the comb is held in the point-contact manner as described above in such a state, a problem that a gripping power suitable for holding the comb is difficult to be obtained occurs.

Moreover, the hair may be set with the comb using lotion with a high viscosity (e.g., a method of setting hair, referred to as “Finger Wave,” which is also a subject of the beautician's state examination), and when setting hair using such lotion with the high viscosity, etc., the user is required to put a remarkable power into the fingers which support the comb. However, since the contacting state of the user's fingers and the comb is the point contact as described above, there is a problem that the power is concentrated on the contacting part of the fingers and the load to the fingers at the contacting part is large. In addition, when the lotion, etc. is adhered to the contacting part of the fingers, the skin of this part may be swollen, and in the state where the skin of the fingers is swollen, if the task with the large load to the fingers described above is performed, the skin of the fingers may possibly be damaged, for example, the skin of this part of the finger where the power which supports the comb is concentrated may peel off.

Further, as the task using the comb, the hair bundle to be cut may be scooped up by the comb, and when performing such a task, since the comb teeth and the edge comb part have the wedged tapered shape as described above, there is a problem that the hair bundle which has been scooped up with considerable effort can more easily slide down from the tip-end side of the comb teeth and the edge comb part. Further, as another example of the task using the comb, a task in which the comb is inserted into the hair and is moved inside the hair to divide the hair in a desired direction is performed (parting task), and when performing this kind of task, since the edge comb part has a greater thickness than comb teeth, the resistance caused by the contact with the hair is large and, thus, there is also a problem that the task to insert the edge comb part into the hair or to move the edge comb part is not smoothly performed.

Note that, regarding the problems described above, in the comb teeth according to Patent Document 2, the bottom surface of the notched part (6) or the central recessed part (7) is a flat shape. Thus, when the fingers are fitted into the notched part (6) or the central recessed part (7), since the fingers only point-contact the flat bottom surface, the gripping power suitable for gripping the comb cannot be obtained and the load on the fingers at the contacting part cannot be reduced. Moreover, since the comb according to Patent Document 3 has the notched groove 3b which is formed by notching into the comb teeth of the corrugated arc shape, when the fingers are fitted into such a groove 3b, the load on the fingers increases due to the corrugated sharp part biting into the fingers.

Moreover, referring to the example of usage illustrated in FIG. 5 of Patent Document 4, since in the ring comb for permanents according to Patent Document 4, the thickness of the illustrated fingers is equal to or more than the length of the comb teeth, and the fingers cover up the comb teeth up to the tip end if the way to grip the comb teeth or the edge comb part with the fingers is performed, and so it does not function as a comb. Thus, it cannot be considered that this holding method can be used for the ring comb for permanents according to Patent Document 4. Further, since the brush for hair coloring according to Patent Document 5 is a brush where the depressed part is formed in the brush base part corresponding to the comb main body, it cannot contribute at all to the way of holding the comb which supports the comb at the comb teeth or the edge comb part. Moreover, although the comb according to Patent Document 1 has the through-holes formed in the tip-end part 2a or the base-end part 2b corresponding to the edge comb part, since the formed parts of the through-holes are not a tip-end portion, these through-holes are not related to the contact of the tip-end portion of the edge comb part with the hair at all.

The present disclosure is made in view of these situations, and one purpose thereof is to provide a comb capable of giving a moderate gripping feel to fingers which support the comb, and reducing a load to the fingers by forming a curved recessed part (comb tooth recessed part) which conforms to the fingers on the comb teeth or an edge comb part.

Another purpose of the present disclosure is to provide a comb of which a gripping performance is further improved by the newly formed recessed part (comb tooth recessed part) forming an edge in a portion connected with a root side.

Further, another purpose of the present disclosure is to provide a comb in which, when a hair bundle is scooped up with the comb, it is made difficult for the scooped-up hair bundle to slide down by the newly formed recessed part (comb tooth recessed part) forming an edge in a portion connected with a tip-end side.

Further, another purpose of the present disclosure is to provide a comb capable of reducing resistance caused in a tip-end part of an edge comb part when inserting the comb into the hair or moving the comb inside the hair by forming a through-hole in a tip-end portion of the edge comb part.

Summary of the Disclosure

In order to solve the problems, a comb according to the present disclosure includes a comb main body, an edge comb part provided to both ends of the comb main body in longitudinal directions, respectively, and a plurality of comb teeth projecting from the comb main body between the edge comb parts at both ends. In each of the adjacent comb teeth included in at least a partial range of the plurality of comb teeth, a comb tooth recessed part of a curved shape based on a concave curve is formed in a middle part between a tip-end side and a root side in at least one of perimeter edges of the comb tooth in width directions. A dimension of a narrowest-width part in the middle part of the comb tooth where the comb tooth recessed part is formed is smaller than a widest-width part on the tip-end side of the comb tooth.

According to the present disclosure, since the comb tooth recessed part entirely having the curved shape based on the concave curve is formed in the middle part of each of the adjacent comb teeth included in the partial range, if a holding method in which the comb teeth are supported by fingers is carried out, the fingers are fitted into each of the comb tooth recessed parts of the adjacent comb teeth, and the fingers fitted into each of the comb tooth recessed parts contact the comb side over a wide area instead of a point contact because of the entire curved shape of the comb tooth recessed parts. By the fingers contacting over such a wide area being fitted into the comb tooth recessed parts, a moderate gripping feel is secured to the fingers which support the comb, power acting on the fingers is distributed to the wide contact locations, and the load on the fingers is reduced. In addition, when a task such as scooping up a hair bundle to be cut is performed by the comb, since the scooped-up hair bundle is fitted into the comb tooth recessed parts, it is made difficult for the scooped-up hair bundle to slide down from the tip-end side of the comb teeth.

Further, a comb according to the present disclosure includes a comb main body, an edge comb part provided to both ends of the comb main body in longitudinal directions, respectively, and a plurality of comb teeth projecting from the comb main body between the edge comb parts at both ends. In at least one of the edge comb parts at both ends, a recessed part of a curved shape based on a concave curve is formed in a middle part between a tip-end side and a root side in at least one of perimeter edges of the edge comb part in width directions. A dimension of a narrowest-width part in the middle part of the edge comb tooth where the recessed part is formed is smaller than a widest-width part on the tip-end side of the edge comb part. In each of the comb teeth included in a range provided to the edge comb part side where at least the recessed part is formed, among the plurality of comb teeth, a comb tooth recessed part of a curved shape based on a concave curve is formed in a part corresponding to the recessed part of the edge comb part in width directions of the comb teeth. A dimension of a narrowest-width part in the middle part of the comb tooth where the comb tooth recessed part is formed is smaller than a widest-width part on the tip-end side of the comb tooth. The recessed part smoothly leads to the comb tooth recessed parts in directions along in the longitudinal directions of the comb main body.

According to the present disclosure, the recessed part is formed in at least one of the edge comb parts at both ends of the comb main body and the comb tooth recessed part is formed in each of the comb teeth belonging to a range provided on the edge comb part side on which the recessed part is formed, so that the recessed part of the edge comb part smoothly leads to the comb tooth recessed part of each of the comb teeth. Therefore, if one holds the comb in such a manner that fingers contact the edge comb part and the comb teeth located in a range near the edge comb part, the fingers are fitted into the recessed part and the comb tooth recessed parts. Since the recessed part and the comb tooth recessed part entirely have the curved shapes, respectively, they easily contact the fingers over a wide area. Thus, a moderate gripping power is obtained, power acting on the contacting locations of the fingers is distributed to the wide area, and the load on the fingers can be reduced.

In addition, when a task such as scooping up a hair bundle to be cut is performed by the comb, since the scooped-up hair bundle is fitted into the recessed part and the comb tooth recessed parts, it is made difficult for the hair bundle to slide down from the tip-end side of the comb teeth and the edge comb part. Note that the dimension of the narrowest-width part of the edge comb part where the recessed part is formed is smaller than the widest-width part on the tip-end side of the edge comb part, and the dimension of the narrowest-width part of the comb tooth where the comb tooth recessed part is formed is smaller than the widest-width part on the tip-end side of the comb tooth. Therefore, both the recessed part and the comb tooth recessed parts become able to secure their sufficient range and depth dimensions so as to achieve the above described effect.

In the comb according to the present disclosure, the recessed part of the edge comb part may be formed in both the perimeter edges on one side and the other side in the width directions.

According to the present disclosure, since the recessed part of the edge comb part is formed in both the perimeter edges in the width directions, the comb tooth recessed parts of the comb teeth which are formed corresponding to the recessed parts are also provided on both sides in the width directions. Thus, even if the comb is gripped from either of the front side or the back side of the comb, the fingers are fitted into the recessed parts and the comb tooth recessed parts, resulted in enhancing a gripping performance of the comb. Further, due to a similar reason, even if a task such as scooping up a hair bundle to be cut is performed by either of the front side or the back side of the comb, the scooped-up hair bundle is fitted into the recessed part and the comb tooth recessed parts, resulted in improving user-friendliness of the comb.

In the comb according to the present disclosure, the recessed part may be formed in both the edge comb parts at both ends.

According to the present disclosure, since the recessed part is formed in both the edge comb parts provided to both ends of the comb main body, even if the comb is gripped from either of the both ends of the comb main body, a thumb is fitted into the recessed part and the comb tooth recessed parts, resulted in further enhancing the gripping performance. Further, due to the similar reason, even if a task such as scooping up a hair bundle to be cut is performed from either of the both ends of the comb main body, the scooped-up hair bundle is fitted into the recessed part and the comb tooth recessed parts, resulted in further improving the user-friendliness of the comb.

In the comb according to the present disclosure, a short comb tooth with a shorter full length than the comb teeth may be provided to the comb main body so that the short comb tooth is adjacent to one of the edge comb parts at both ends. The comb tooth recessed part may be formed in the plurality of adjacent comb teeth other than the short comb tooth.

According to the present disclosure, since the short comb tooth is provided to be adjacent to one of the edge comb parts, even if the recessed part and the comb tooth recessed part are provided, a task of forming a parting line of hair (parting task) is performed by the one of the edge comb part. In addition, since the comb tooth recessed part are formed in the plurality of adjacent comb teeth, it is suitable to a task such as scooping up a large hair bundle, and efficiency of the task using the comb is improved.

In the comb according to the present disclosure, an edge may be formed in a portion where the recessed part and the root side in the edge comb part are connected with each other.

According to the present disclosure, since the edge is formed in the portion where the recessed part and the root side in the edge comb part are connected, the finger fitted into the recessed part is caught at the edge. Thereby, the gripping performance of the finger holding the comb is further enhanced and the edge can be useful as an antiskid for the finger holding the comb.

In the comb according to the present disclosure, an edge may be formed in a portion where the comb tooth recessed part and the root side in the comb tooth are connected with each other.

According to the present disclosure, since the edge is formed in the portion where the comb tooth recessed part and the root side in the comb tooth are connected, the finger fitted into the comb tooth recessed parts is caught at the edge of each comb tooth. Thereby, the gripping performance of the finger holding the comb is further enhanced and the antiskid function for the finger holding the comb is further improved.

In the comb according to the present disclosure, an edge may be formed in a portion where the recessed part and the tip-end side in the edge comb part are connected with each other.

According to the present disclosure, since the edge is formed in the portion where the recessed part and the tip-end side in the edge comb part are connected, the hair bundle fitted into the recessed part is caught at the edge during the scooping-up by the comb, and it becomes further difficult for the scooped-up hair bundle to slide down from the comb teeth and the edge comb part.

In the comb according to the present disclosure, an edge may be formed in a portion where the comb tooth recessed part and the tip-end side in the comb tooth are connected with each other.

According to the present disclosure, since the edge is formed in the portion where the comb tooth recessed part and the tip-end side in the comb tooth are connected, the hair bundle fitted into the comb tooth recessed part is caught at the edge during the scooping-up by the comb, and it becomes further more difficult for the scooped-up hair bundle to slide down from the comb teeth and the edge comb part.

In the comb according to the present disclosure, the recessed part and the comb tooth recessed part may be made into the same curved shape based on the concave curve of the same curvature.

According to the present disclosure, since the recessed part and the comb tooth recessed part are made into the same curved shape based on the concave curve of the same curvature, the recessed part and the comb tooth recessed part are continuously connected smoothly in the same shape. Thereby, the feeling of touching the comb by the fingers fitted in the recessed part and the comb tooth recessed parts is improved and the hair bundle scooped up by the comb becomes easily fitted into the recessed part and the comb tooth recessed parts smoothly, which improves workability of the comb.

In the comb according to the present disclosure, a tip end through-hole penetrating in the width directions of the edge comb part may be formed in a part of the edge comb part within a range from the recessed part to the tip-end sides.

According to the present disclosure, the tip end through-hole penetrating in the width directions of the edge comb part is formed in the part of the edge comb part on the tip-end side from the recessed part. Therefore, in a case of inserting the tip end of the comb into the hair, moving the comb inside the hair, etc., although conventionally the edge comb part has generated the resistance caused by the contact with the hair because the edge comb part has a greater thickness than comb teeth, by forming the tip end through-hole on the tip-end side of the edge comb part, contact range with the hair is reduced because of the opening of the tip end through-hole and the tip end of the edge comb part becomes easy to move against the hair. Further, since the recessed part of the edge comb part and the comb tooth recessed parts of the comb teeth also loosen the contact state with the hair, the work such as inserting the tip end of the comb into the hair and moving the comb inside the hair becomes easier to perform than with the conventional comb.

Effect of the Disclosure

According to the present disclosure, since the comb tooth recessed part having the curved shape entirely based on the concave curve is formed in the middle part of each of the adjacent comb teeth included in the partial range, the fingers fitted into each of the comb tooth recessed parts contact to the comb side over a wide range, the moderate gripping feel is secured to the fingers which support the comb, the power acting on the fingers is distributed to the wide contact locations, and the load on the fingers is reduced.

Further, since the recessed part of the edge comb part is formed in addition to the comb tooth recessed parts of the comb teeth, even if the comb is gripped from either one of the front side or the back side of the comb, the thumb is fitted into the recessed part and the comb tooth recessed parts. Thus, the gripping performance of the comb is enhanced without considering the direction of the comb and the load on the fingers which support the comb is reduced. Further, even if the task of scooping up a hair bundle to be cut, etc. is performed without considering the direction of the comb, the scooped-up hair bundle is fitted into the recessed part and the comb tooth recessed parts, resulted in improving the user-friendliness of the comb.

According to the present disclosure, since the recessed part and the comb tooth recessed part are made into the same curved shape based on the concave curve of the same curvature, the recessed part and the comb tooth recessed part are continuously and smoothly connected in the same shape. Thereby, the feeling of touching the comb by the finger fitted in the recessed part and the comb tooth recessed part is improved and the hair bundle scooped up by the comb is fitted into the recessed part and the comb tooth recessed part smoothly. Thus, the task of scooping up the hair bundle using the comb is performed efficiently.

According to the present disclosure, since the recessed part is formed in both the edge comb parts provided to the both ends of the comb main body, even if the comb is gripped from either of the both ends of the comb main body in the longitudinal direction, the thumb is fitted into the recessed part and the comb tooth recessed part, resulting in further enhancing the gripping performance. Further, due to a similar reason, even if the task of scooping up a hair bundle to be cut, etc. is performed by mainly using either one of the ends of the comb main body in the longitudinal direction, the scooped-up hair bundle is fitted into the recessed part and the comb tooth recessed parts, resulted in further improving the user-friendliness of the comb.

According to the present disclosure, since the short comb tooth is provided to be adjacent to one of the edge comb parts, even if the recessed part and the comb tooth recessed part are provided, a task of forming a parting line of hair (parting task) is performed by the one of the edge comb parts. In addition, since the comb tooth recessed part are formed over the entire range, it is suitable for a task of scooping up a large hair bundle, etc. and the efficiency of the task using the comb is improved.

According to the present disclosure, since the edge is formed in the portion where the recessed part and the root side are connected in the edge comb part, the finger fitted into the recessed part and the comb tooth recessed part is caught at the edge. Thereby, the gripping performance of the finger holding the comb is enhanced and the edge can be useful as an anti skid.

According to the present disclosure, since the edge is also formed in the portion where the comb tooth recessed part and the root side are connected in the comb tooth, the finger fitted into the recessed part and the comb tooth recessed part is caught at the edge of each comb tooth. Thereby, the gripping performance of the finger holding the comb is further enhanced and the antiskid function for the finger holding the comb is further improved.

According to the present disclosure, since the edge is formed in the portion where the recessed part and the tip-end side are connected in the edge comb part, the hair bundle fitted into the recessed part and the comb tooth recessed part is caught at the edge during the scooping-up by the comb, and it prevents the scooped-up hair bundle from sliding down from the comb teeth and the edge comb part.

According to the present disclosure, since the edge is also formed in the portion where the comb tooth recessed part and the tip-end side are connected in the comb tooth, the hair bundle fitted into the recessed part and the comb tooth recessed part is caught at the edge of each comb tooth during the scooping-up by the comb, and the prevention for the scooped-up hair bundle from sliding down from the comb teeth and the edge comb part is further increased.

According to the present disclosure, since the tip end through-hole penetrating in the width directions of the edge comb part is formed in the part of the edge comb part within a range from the recessed part to the tip end side, contact range of the tip end portion of the edge comb part with the hair is reduced and the task such as inserting the tip end of the comb into the hair and moving the comb inside the hair becomes easier to perform than with the conventional comb.

MODES FOR CARRYING OUT THE DISCLOSURE Example 1

FIG. 1 is a perspective view schematically illustrating the entire of a comb 1 according to a first embodiment of the present disclosure. The comb 1 of the present disclosure is made of synthetic resin, and it has a structure such that edge comb parts (one-end edge comb part 3 and the other-end edge comb part 4) project from both ends (one end side 2 a and the other end side 2 b) of an extended bar-shaped comb main body 2 in longitudinal directions, and a plurality of comb teeth 6 project from the comb main body 2 between the one-end edge comb part 3 and the other-end edge comb part 4. Note that an X-axis direction illustrated in FIG. 1 is a direction along the longitudinal directions of the comb 1 (comb main body 2), a Y-axis direction perpendicular to the X-axis direction is a direction along the projecting direction of the comb teeth 6 and the respective edge comb parts 3 and 4, and a Z-axis direction perpendicular to the X-axis direction and the Y-axis direction is a direction along width directions of the comb 1 (comb main body 2), the respective edge comb parts 3 and 4, and the respective comb teeth 6 (similar in other figures). Below, the comb 1 is described in detail.

As illustrated in FIGS. 1, 2(a), 4(a), etc., in the comb main body 2, a plurality of through-holes 7 penetrating from a first surface 2 c corresponding to the front surface to a second surface 2 d corresponding to the opposite back surface are formed along the Z-axis direction, and these plurality of through-holes 7 are, fundamentally, arranged so as to be linearly spaced from each other at a given interval in the X-axis direction. The through-hole 7 is an ellipse which is elongated in the X-axis direction, and an elliptical counter bore 7 a is formed around the ellipse (see also FIG. 3(b)). Note that, in the first embodiment, the ratio of the inner diameter on the long axis side of the through-hole 7 to the inner diameter on the short axis side is set to 2:1, and as one example, the inner diameter on the long axis side is set to about 4 mm (millimeter) and the inner diameter on the short axis side is set to about 2 mm (note that, for the counter bore 7 a, it may be considered that the inner diameter on the long axis side is set to about 9 mm and the inner diameter on the short axis side is set to about 3 mm, for example).

As illustrated in FIG. 2(a), the through-hole 7 located closest to one end side 2 a of the comb main body 2 is formed so that its center is at a position distant by a distance L from an outer edge of the one-end edge comb part 3 provided to the one end side 2 a of the comb main body 2 (a part of the range of a root side 3 b of one-end outer edge surface 3 d, which is the surface of the outer edge of the one-end edge comb part 3). The through-holes 7 which are the second and following through-holes in the order from the one end side 2 a are formed at positions so that the interval of the centers of the through-holes 7 is the distance L, respectively. As one concrete example of the distance L, it may be set to a dimension by the millimeter unit or the inch unit according to the product destination, specification, etc. of the comb 1, and for example, if the dimension by the millimeter unit is used, it is suitable to be set to 10 mm etc. which is the most standard dimension, and if the dimension by the inch unit is used, it is suitable to be set to 1 inch, 0.5 inches, etc. The plurality of through-holes 7 formed at such an interval are usable as markers or indexes indicating a given dimension at every distance L (markers indicating the distance along the longitudinal directions of the comb main body 2).

Moreover, as illustrated in FIG. 4(a), also at the other end side 2 b of the comb main body 2, the plurality of through-holes 7 are formed at an interval (distance L) similar to the one end side 2 a described above from an outer edge of the other-end edge comb part 4 provided to the other end side 2 b of the comb main body 2 (a part of the range on the root side 4 b of the other-end outer edge surface 4 d which is the surface of the outer edge of the other-end edge comb part 4). Note that, in a central part 2 e of the comb main body 2 in the longitudinal directions 2 (see FIG. 1), the through-hole 7 is not formed in order to make the side at which a task of the comb 1 is performed function as a grip part when this side is changed between the one end side 2 a and the other end side 2 b (the side which is used for the task of the comb is changed to the one end side 2 a or the other end side 2 b by rotating the comb centering on the part gripped so that the central part 2 e of the comb main body 2 is pinched).

As illustrated in FIG. 1, etc., in the comb 1, the plurality of comb teeth 6 are provided to the comb main body 2 so that they become parallel to the one-end edge comb part 3 and the other-end edge comb part 4, and regarding these comb teeth 6, in the longitudinal directions of the comb main body 2, as for a first range 1 a (a range on the one-end edge comb part 3 side) which extends from the center of the central part 2 e of the comb main body 2 to the one end side 2 a, and a second range 1 b (a range on the other-end edge comb part 4 side) which extends from the center of the central part 2 e to the other end side 2 b, the interval at which the respective comb teeth 6 are formed (comb teeth pitch) is different so that the comb teeth pitch in the first range la is larger than the comb teeth pitch in the second range 1 b (one example of the comb teeth pitch in the first range 1 a may be considered to be about 3 mm, and one example of the comb teeth pitch in the second range 1 b may be considered to be about 1.5 mm).

Thus, by differentiating the comb teeth pitches between the first range 1 a and the second range 1 b, different kinds of hairdressing tasks can be performed by the single comb 1, and for example, a rough hairdressing task may be performed with the first range 1 a side and a fine hairdressing task may be performed with the second range 1 b, and therefore, as described above, it is significant to change the side of the comb which is used for the task to the one end side 2 a or the other end side 2 b. Note that, the comb teeth 6 included in the first range 1 a and the comb teeth 6 included in the second range 1 b are differentiated in the thickness (a dimension of the comb teeth in the X-axis direction), and the thickness of the comb teeth 6 included in the first range 1 a is a little more than about 1 mm, while the thickness of the comb teeth 6 included in the second range 1 b is about 0.6 to 0.8 mm.

Moreover, in the comb 1, among the plurality of comb teeth 6, a short comb tooth 6′ is provided at a part adjacent to the one-end edge comb part 3 in the first range 1 a, which is shorter in the projecting dimension (full length in the Y-axis direction) than that of other comb teeth 6 having a normal length. Thus, when performing a task to form a parting line of hair (parting task) by the one-end edge comb part 3, the parting task is made easier because a space is produced around a tip end 3 v (see FIG. 2(b)) of the one-end edge comb part 3. Note that, the thickness of the short comb tooth 6′ is a little more than about 1 mm.

As illustrated in FIG. 1, and FIGS. 2(a) and (b), the one-end edge comb part 3 has a tapered shape of which the point is narrowed and sharpened, projects from the one end side 2 a of the comb main body 2 in a direction perpendicular to the comb main body 2 (a direction along the Y-axis direction), and encloses and protects the comb teeth 6. In FIG. 2(a) which is a front view, the one-end edge comb part 3 can be divided, in a direction along the Y-axis direction, into a range on a tip-end side 3 a having a tapered tip end 3 v, a range on the root side 3 b connected with the comb main body 2, and a range of a middle part 3 c which is between the tip-end side 3 a and the root side 3 b. Although the ratio of these ranges can be set variously according to a design and a specification, if the full length along the Y-axis direction of the one-end edge comb part 3 is set to “1,” it is suitable that the tip-end side 3 a and the root side are set to “about 0.3,” and the middle part 3 c is set to “about 0.4” so that the middle part 3 c is made somewhat wider than the other two ranges, and one-end depressed part 3 e illustrated in FIG. 2(a), and a first recessed part 3 h and a second recessed part 3 i illustrated in FIG. 2(b) secure necessary dimensions for a user's fingers, etc., respectively.

In the one-end edge comb part 3, the one-end depressed part 3 e of a curved shape based on a concave curve is formed in an edge which is the perimeter (the one-end outer edge surface 3 d which is a surface forming the edge of the perimeter), in the front view of FIG. 2(a). It is suitable for the curvature according to this one-end depressed part 3 e (a curvature of the concave curve) to be slightly smaller than the smallest curvature part in the head of a common human body, and in the example illustrated in FIG. 2(a), it is 50 mm in the radius of curvature. Note that, at the root side 3 b of the one-end edge comb part 3, the one-end outer edge surface 3 d is formed in almost a flat surface, and at the tip-end side 3 a of the one-end edge comb part 3, it is an outwardly convex curve (a curved surface) so that it is narrowed as approaching to the tip end 3 v.

The one-end edge comb part 3 becomes, by forming the one-end depressed part 3 e described above, in a shape so that parts of the one-end outer edge surface 3 d which are located on both sides of the one-end depressed part 3 e (the tip-end side 3 a and the root side 3 b) in the Y-axis direction project. Thus, when the one-end outer edge surface 3 d is abut on the scalp of the head of the human body, it becomes 2-point contact to the scalp at the parts of the one-end outer edge surface 3 d on both sides of the one-end depressed part 3 e, the stable posture of the comb 1 can be secured, and by using the through-holes 7 described above are used for a scale, and the comb 1 in the stable posture can measure a rough length of the hair which grows from the scalp.

Further, as illustrated in FIGS. 2(a) and 9, the one-end edge comb part 3 forms a tip end through-hole 8 penetrating in the Z-axis direction (width direction) at the tip-end side 3 a. Similar to the through-holes 7 of the comb main body 2, the tip end through-hole 8 is an ellipse and forms an elliptical counter bore 8 a around the ellipse (see FIG. 9). Note that, the tip end through-hole 8 is arranged so that its long-axis direction is oblique with respect to the Y-axis direction and, thus, the outer edge on the tip-end side 3 a which has the tapered shape is arranged so that an opening edge of the counter bore 8 a of the tip end through-hole 8 is along an outwardly convex curve (a curved surface) to secure the possibly largest openings of the elliptical tip end through-hole 8 and the elliptical counter bore 8 a.

FIG. 2(b) illustrates the one-end edge comb part 3 in a state where it is seen from the one-end outer edge surface 3 d, and the shape of the one-end edge comb part 3 is laterally symmetrical in the state when seen from this direction. In the one-end edge comb part 3, a first recessed part 3 h and a second recessed part 3 i, which have entirely a curve-shaped based on the an arc-shaped concave curve, are formed in the middle part 3 c (the part between the tip-end side 3 a and the root side 3 b) of one perimeter edge 3 f (an edge on the same side as the first surface 2 c which is the front side of the comb main body 2) and the other perimeter edge 3 g (an edge on the same side as a second surface 2 d which is the back side of the comb main body 2), in the width directions (a direction parallel to the Z-axis direction) respectively. Note that, although each of the perimeter edges 3 f and 3 g are expressed by a “line” in FIG. 2(b), it is actually a “surface” as is clear in the front view according to FIG. 2(a), and therefore, the first recessed part 3 h and the second recessed part 3 i are also actually smooth “curved surfaces.”

Moreover, in the one-end edge comb part 3, the perimeter edges 3 f and 3 g on both sides of the root side 3 b are almost flat surfaces, and the perimeter edges 3 f and 3 g on both sides of the tip-end side are the curves (curved surfaces) which are outwardly convex so that the one-end edge comb part 3 is narrowed as it approaches the tip-end part.

The first recessed part 3 h formed in the middle part 3 c of the one perimeter edge 3 f is made into a smooth arc-shaped concave curve (curved surface) which is convex centering the deepest part so that it is toward the center of the one-end edge comb part 3 within a nearby range. Note that, the parts on the tip-end side 3 a and the root side 3 b in the perimeter edge 3 f centering on the first recessed part 3 h are provided with points of inflection, parts further on the tip-end side 3 a and the root side 3 b from these points of inflection are made into smooth curves (curved surfaces) which are outwardly convex. Thus, the first recessed part 3 h is connected with the tip-end side 3 a by the smooth curve (curved surface) and is also connected with the root side 3 b by the smooth curve (curved surface). Thus, the formed state of the curve (curved surface) of the first recessed part 3 h is applied to the second recessed part 3 i of the other perimeter edge 3 g.

A radius of curvature R1 according to the concave curve which forms the first recessed part 3 h and the second recessed part 3 i is made into the curvature dimension corresponding to an average value of a thumb which is the thickest among human fingers, and in the example illustrated in FIG. 2(b), it is about 30 mm.

Moreover, the deepest parts of the first recessed part 3 h and the second recessed part 3 i correspond to the narrowest part (third part 3 n) in the width of the middle part 3 c, and a width W3 of the third part 3 n is smaller than a width W1 of a first part 3 j which is the widest at the tip-end side 3 a (W3<W1), and the width W3 of the third part 3 n is also smaller than a width W2 of a second part 3 k which is wide at the root side 3 b (W3<W2). Note that, the width W2 of the second part 3 k is made larger than the width W1 of the first part 3 j (W2>W1). Thus, by making the width W3 of the third part 3 n smallest, the first recessed part 3 h and the second recessed part 3 i which are formed in the middle part 3 c can secure a sufficient depth at the tip-end side 3 a and the root side 3 b.

FIG. 3(a) illustrates a cross-section taken along a line A-A in FIG. 2(a), and illustrates the short comb tooth 6′ provided adjacent to the one-end edge comb part 3. As illustrated in FIG. 3(a), the short comb tooth 6′ has a substantially tapered wedge shape which is laterally symmetrical when seen from a direction along the X-axis direction, a width of a root part 6 b′ on the comb main body 2 side is a width W4, and this width W4 is less than the width W2 on the root side 3 b of the one-end edge comb part 3 described above. Moreover, a tip-end part 6 a′ of the short comb tooth 6′ is located within a range corresponding to the middle part 3 c of the one-end edge comb part 3 described above, and a width W5 of the tip-end part 6 a′ is made smaller than the width at any location of the first recessed part 3 h and the second recessed part 3 i of the one-end edge comb part 3, and when it is seen in the X-axis direction, the contours of the tip-end part 6 a′ and the root part 6 b′ do not extend outwardly from the curves (curved surfaces) according to the first recessed part 3 h and the second recessed part 3 i. Note that, if it is difficult to fall the contour of the short comb tooth 6′ within the curves according to the first recessed part 3 h and the second recessed part 3 i of the one-end edge comb part 3, a recessed part is also formed in the short comb tooth 6′ by denting the part to be outwardly protruded.

FIG. 3(b) illustrates a cross-section taken along a line B-B in FIG. 2(a), and illustrates the comb tooth 6. The comb tooth 6 illustrated in FIG. 3(b) is one example of the plurality of comb teeth 6 of the comb 1, and all of the plurality of comb teeth 6 have a similar structure to the comb tooth 6 illustrated in FIG. 3 (note that the short comb tooth 6′ is excluded). When seen from the direction along the X-axis direction, the comb tooth 6 also has a tapered shape which is laterally symmetrical, and it can be divided along the Y-axis direction into a range on a tip-end side 6 a having a tapered tip end 6 v, a range on a root side 6 b connected with the comb main body 2, and a range of a middle part 6 c which is between the tip-end side 6 a and the root side 6 b. The tip end 6 v of the comb tooth 6 is at the same position in the projecting direction as the tip end 3 v of the one-end edge comb part 3 described above, a range of the tip-end side 6 a of the comb tooth 6 corresponds in the position and dimension to the range on the tip-end side 3 a of the one-end edge comb part 3, the range of the middle part 6 c of the comb tooth 6 corresponds in the position and dimension to the range of the middle part 6 c of the one-end edge comb part 3, and a range of the root side 6 b of the comb tooth 6 corresponds in the position to the range of the middle part 3 c in the root side 3 b of the one-end edge comb part 3 (the dimension of the range on the root side 6 b in the comb tooth 6 is about 1/3 of the dimension of the root side 3 b of the one-end edge comb part 3).

In the comb tooth 6, in the middle part 6 c of perimeter edges 6 f and 6 g on both sides in the width directions (Z-axis direction), when seen from a direction illustrated in FIG. 3(b), a first comb tooth recessed part 6 h and a second comb tooth recessed part 6 i, which are entirely a curve shape based on a smooth arc-shaped concave curve, are formed in parts corresponding to the first recessed part 3 h and the second recessed part 3 i of the one-end edge comb part 3 which are described above, respectively. The shape of the first comb tooth recessed part 6 h and the second comb tooth recessed part 6 i has a similar structure to and the same shape as the first recessed part 3 h and the second recessed part 3 i of the one-end edge comb part 3. A radius of curvature R2 according to the concave curve in the deepest part of the first comb tooth recessed part 6 h and the second comb tooth recessed part 6 i has the same dimension as the radius of curvature R1 according to the first recessed part 3 h and the second recessed part 3 i and, thus, the first comb tooth recessed part 6 h and the second comb tooth recessed part 6 i (comb tooth recessed parts) have a curved shape of the same shape and the same size as the first recessed part 3 h and the second recessed part 3 i (recessed parts), respectively.

Moreover, also in the comb teeth 6, a width W8 of the third part 6 n which is the narrowest width in the middle part 6 c (the deepest part of the first comb tooth recessed part 6 h and the second comb tooth recessed part 6 i) is made smaller than a width W6 of a first part 6 j which is the widest in the tip-end side 6 a (W8<W6), and the width W8 of the third part 6 n is smaller a width W7 of a second part 6 k which is wider in the root side 6 b (W8<W7). Note that, the width W8 of the second part 6 k is larger than the width W6 of the first part 6 j (W7>W6). Thus, also in the comb teeth 6, by making the width W8 of the third part 6 n in the middle part 6 c the smallest, the first comb tooth recessed part 6 h and the second comb tooth recessed part 6 i which are formed in the middle part 6 c can secure sufficient depths.

By the above structure, in the front side of the comb 1 (the first surface 2 c side of the comb main body 2), the first recessed part 3 h of the one-end edge comb part 3 has a structure in which it smoothly leads to the first comb tooth recessed part 6 h of the comb tooth 6 located nearby having the short comb tooth 6′ therebetween in the directions along the longitudinal directions of the comb main body 2, and they are smoothly continuous, and similarly, also in the back side of the comb 1 (the second surface 2 d side of the comb main body 2), the second recessed part 3 i of the one-end edge comb part 3 has a structure in which it smoothly leads to the second comb tooth recessed part 6 i of the comb tooth 6 located nearby having the short comb tooth 6′ therebetween, and they are smoothly continuous.

The comb teeth 6 having the structure described above are common to those included in the first range 1 a of a wide pitch illustrated in FIG. 1 and those included in the second range 1 b of a narrow pitch, the first comb tooth recessed parts 6 h of the respective comb teeth 6 included in the first range 1 a and the second range 1 b have the structure in which they are smoothly continuous (communicating with each other) at the front side of the comb 1 (the first surface 2 c side of the comb main body 2), and the second comb tooth recessed parts 6 i of the respective comb teeth 6 included in the first range 1 a and the second range 1 b have the structure in which they are smoothly continuous (communicating with each other) at the back side of the comb 1 (the second surface 2 d side of the comb main body 2).

FIG. 4(a) is a front view illustrating a substantial part of the other-end edge comb part 4 of the comb 1, and the other-end edge comb part 4 is fundamentally laterally symmetrical with respect to the one-end edge comb part 3 illustrated in FIG. 2(a) etc. described above. That is, the other-end edge comb part 4 is divided into a range of a tip-end side 4 a which has a tapered shape of which the point is narrowed and sharpened, extends in a direction along the Y-axis direction from the other end side 2 b of the comb main body 2, and has a tapered tip end 4 v, a range of a root side 4 b connected with the comb main body 2, and a range of a middle part 4 c, and the other-end depressed part 4 e of a curve shape is formed in the other-end outer edge surface 4 d of the middle part 4 c. The other-end edge comb part 4 forms, at the tip-end side 4 a, an elliptical tip end through-hole 9 penetrating in the Z-axis direction (width direction), and this tip end through-hole 9 has an elliptical counter bore 9 a.

Moreover, FIG. 4(b) illustrates a state of the other-end edge comb part 4 when seen from the other-end outer edge surface 4 d, and also when it is seen from this direction, the shape of the other-end edge comb part 4 is laterally symmetrical with the one-end edge comb part 3 described above. That is, in the other-end edge comb part 4, a first recessed part 4 h and a second recessed part 4 i which are entirely a curved shape based on a concave curved shape are formed in the middle part 4 c (a part between the tip-end side 4 a and the root side 4 b) of one perimeter edge 4 f (an edge on the same side as the first surface 2 c which is the front side of the comb main body 2) in the width directions (directions parallel to the Z-axis direction) and the other perimeter edge 4 g (an edge on the same side as the second surface 2 d which is the back side of the comb main body 2), respectively (the first recessed part 4 h and the second recessed part 4 i have a similar structure to the first recessed part 3 h and the second recessed part 3 i of the one-end edge comb part 3 which are described above, respectively).

Also in the other-end edge comb part 4, a width W3 of a third part 4 n which is the narrowest in the middle part 4 c is made smaller than a width W1 of the first part 4 j which is the widest in the tip-end side 4 a (W3<W1), and the width W3 of the third part 4 n is made also smaller than a width W2 of the second part 4 k which is wider in the root side 3 b (W3<W2). Note that, the width W2 of the second part 4 k is larger than the width W1 of the first part 4 j (W2>W1).

By the above structure of the other-end edge comb part 4, also at the other-end edge comb part 4 side, on the front side of the comb 1 (the first surface 2 c side of the comb main body 2), the first recessed part 4 h of the other-end edge comb part 4 smoothly leads to the first comb tooth recessed parts 6 h of the respective comb teeth 6 located nearby, and both are smoothly continuous, and at the back side of the comb 1 (the second surface 2 d side of the comb main body 2), and the second recessed part 4 i of the other-end edge comb part 4 smoothly leads to the second comb tooth recessed parts 6 i of the comb teeth 6 located nearby, and both are smoothly continuous.

Therefore, the entire comb 1 has the structure so that, in the entire range from the one-end edge comb part 3 to the other-end edge comb part 4 through the plurality of comb teeth 6, on the front side of the comb 1 (the first surface 2 c side of the comb main body 2), the first recessed part 3 h of the one-end edge comb part 3, the first comb tooth recessed parts 6 h of the plurality of comb teeth 6, and the first recessed part 4 h of the other-end edge comb part 4 smoothly leads to each other and are smoothly continuous, and also on the back side of the comb 1 (the second surface 2 d side of the comb main body 2), the second recessed part 3 i of the one-end edge comb part 3, the second comb tooth recessed parts 6 i of the plurality of comb teeth 6, and the second recessed part 4 i of the other-end edge comb part 4 smoothly leads to each other and are smoothly continuous.

FIG. 5 illustrates a case where the user holds the comb 1 according to the first embodiment by supporting the other-end edge comb part 4 and the plurality of comb teeth 6 located within a range near the other-end edge comb part 4 with a thumb F1.

FIG. 6(a) illustrates a state of the other-end edge comb part 4 in the state illustrated in FIG. 5 when seen from the other-end outer edge surface 4 d (a state when seen from the same direction as FIG. 4(b)), the user's thumb F1 is fitted into the first recessed part 4 h formed in the middle part 4 c of the one perimeter edge 4 f on the same side as the front side of the comb 1 (the first surface 2 c side of the comb main body 2). Since the first recessed part 4 h is connected with the tip end 4 a and the root side 4 b by the smooth curves in the Y-axis directions, when the user's thumb F1 touches the one perimeter edge 4 f of the other-end edge comb part 4 for gripping, the thumb F1 is smoothly guided into the first recessed part 4 h by touch from either the tip-end side 4 a or the root side 4 b, and is naturally fitted into the first recessed part 4 h.

Moreover, FIG. 6(b) illustrates a cross-section taken along a line C-C of the state illustrated in FIG. 5, and the user's thumb F1 is fitted into the first comb tooth recessed part 6 h formed in the middle part 6 c of the one perimeter edge 6 f on the same side as the front side of the comb 1 (the first surface 2 c side of the comb main body 2). Since this first comb tooth recessed part 6 h is connected with the tip-end side 6 a and the root side 6 b by the smooth curves in the Y-axis directions, when the user's thumb F1 touches the one perimeter edge 6 f of the comb teeth 6 for gripping, the thumb 1 is smoothly guided into the first comb tooth recessed part 6 h from either the tip-end side 6 a or the root side 6 b, and it is naturally fitted into the first comb tooth recessed part 6 h. Note that, a relation between the comb teeth 6 in the part touched by the thumb F1 other than the part according to the line C-C and the thumb F1 becomes a similar state to the state illustrated in FIG. 6(b).

Moreover, since the first recessed part 4 h of the other-end edge comb part 4 smoothly leads to the respective first comb tooth recessed parts 6 h, having the same shape with the first recessed part 4 h, of the plurality of comb teeth 6 located within a range adjacent to the other-end edge comb part 4. Thus, one finger (the thumb) is fitted into a space formed by the first recessed part and the plurality of first recessed parts 6 h across these parts. In this state, since the first recessed part 4 h and the first comb tooth recessed parts 6 h have the curved shapes, a curved cushion part of the thumb F1 becomes in a surface contact instead of a point contact and, thus, the thumb F1 contacts the comb 1 with a larger range than the conventional arts. Therefore, when supporting the comb 1, the load acting on the thumb F1 is distributed and the gripping power over the comb 1 increases, and the first recessed part 4 h and the first comb tooth recessed parts 6 h is also useful as an antiskid. Moreover, if the user carries out the holding method at the back side of the comb 1 (the second surface 2 d side of the comb main body 2) so that an index finger F2 touches the middle part 6 c of the comb teeth 6, the index finger F2 is also fitted into the second comb tooth recessed parts 6 i of the respective comb teeth 6 in a part touched by the index finger F2, the comb 1 can be supported by a surface contact and the moderate gripping power over the index finger F2 can be secured, and since the index finger F2 also surface-contacts the plurality of second comb tooth recessed parts 6 i of the curved shape, power required for supporting the comb can be distributed and the load on the index finger F2 can be reduced.

Thus, in the comb 1 according to the first embodiment, it is easy to put the power into the thumb F1 and the index finger F2 which support the comb 1, and the workability using the comb 1 according to the first embodiment is improved compared with the conventional combs. Note that, although in FIGS. 5, 6(a) and 6(b), the case where the other-end edge comb part 4 side is gripped is illustrated, even when the one-end edge comb part 3 side is gripped, the situation becomes similar to that described above, and especially since the short comb tooth 6′ adjacent to the one-end edge comb part 3 does not protrude into the space formed by the first recessed part 3 h and the first comb tooth recessed parts 6 h, the short comb tooth 6′ does not disturb that the thumb is fitted into the first recessed part 3 h and the first comb tooth recessed parts 6 h.

FIG. 7(a) illustrates the way to grip the comb 1 according to the first embodiment when performing a hair set called the “finger wave.” In this case, the index finger F2, the middle finger F3, and the third finger F4 support the front side of the comb 1 (the first surface 2 c side), and the thumb F1 and the little finger F5 support the back side of the comb 1 (the second surface 2 d side). Specifically, the index finger F2, the middle finger F3, and the third finger F4 which support the front side (the first surface 2 c side) are fitted at their fingertips into a space formed by the first comb tooth recessed parts 6 h of the one perimeter edges 6 f of the plurality of comb teeth 6. Thus, moderate gripping can be obtained at each of the fingers F2-F4, and the load on each of the fingers F2-F4 due to the surface contact can be reduced.

Moreover, the thumb F1 and the little finger F5 which support the back side (the second surface 2 d side) are fitted into a space formed by the second comb tooth recessed parts 6 i of the other perimeter edge 6 g of the plurality of comb teeth 6. Here, the thumb F1 contacts the second comb tooth recessed parts 6 i in a wide range at its fingertip (a cushion part of the fingertip) to obtain the moderate gripping and reduce the load on the thumb F1; however, regarding the little finger F5, its back-side part contacts the second comb tooth recessed parts 6 i.

FIG. 7(b) illustrates a situation of supporting the comb 1 by the little finger F5 when performing the finger wave. The little finger F5 is in a situation where its back-side part is fitted into the second comb tooth recessed parts 6 i formed on the other perimeter edge 6 g side of the plurality of comb teeth 6. Since the second comb tooth recessed parts 6 i have entirely a curved shape, they become in a state where they surface-contact the back-side part of the little finger F5 in a wide range and, thus, it avoids that the power which supports the comb 1 concentrates on one point in the back-side part of the little finger F5, thereby reducing the load on the back-side part of the little finger F5. Thus, when performing a hair set of the finger wave with the comb 1 using lotion with a high viscosity, even if power is put into each of the fingers F1-F5 with the holding method illustrated in FIGS. 7(a) and (b), the load to each of the fingers F1-F5 is reduced compared with the conventional combs, and especially for the little finger F5 which supports the comb at the back side of the finger, since the skin is weaker at the back side of the finger than the cushion side of the finger, the merit by the load reduction is large, and further, the merit of the load reduction when the skin has swollen by adhesion of the lotion etc. can largely contribute to the user.

FIG. 8(a) illustrates one example in which a task to scoop up a hair bundle using the comb 1 according to the first embodiment is performed, and in this example, it is assumed to be in a situation where the other-end edge comb part 4 side is gripped with the fingers and the hair bundle is scooped up by the one-end edge comb part 3 side and the back side of the comb 1 (the second surface 2 d side of the comb main body 2).

FIG. 8(b) illustrates a situation of scooping-up of the hair bundle in the one-end edge comb part 3, where the scooped-up hair bundle h is fitted into the second recessed part 3 i formed in the middle part 3 c of the other perimeter edge 3 g which becomes an upper surface in FIG. 8(b). That is, since the second recessed part 3 i is connected with the tip-end side 3 a and the root side 3 b by the smooth curves in the Y-axis directions, the hair bundle h scooped up by the other perimeter edge 3 g (upper surface in FIG. 8(b)) of the one-end edge comb part 3 is guided by the smooth curved surface to the second recessed part 3 i, and is naturally fitted into the second recessed part 3 i.

Moreover, FIG. 8(c) illustrates a situation of scooping-up of the hair bundle h by one of the comb teeth 6 located near the one-end edge comb part 3. Also in this comb tooth 6, similar to the case of the one-end edge comb part 3 illustrated in FIG. 8(b), the scooping-up hair bundle h is fitted into the second comb tooth recessed part 6 i formed in the middle part 6 c of the other perimeter edge 6 g which is the upper surface. Thus, when the task, such as scooping up the hair bundle using the comb 1 of the first embodiment is performed, since the scooped-up hair bundle is fitted into the space formed by the second recessed parts 3 i of the one-end edge comb part 3 and the second comb tooth recessed parts 6 i of the respective comb teeth 6 located nearby, the frequency of the hair bundle scooped up by the comb slides down from the tip-end side like the conventional arts decreases, and the efficiency of the task to scoop up the hair bundle with the comb can be improved.

Note that, although in the example described above the case where the scooping-up task is performed on the back side of the comb 1 on the one-end edge comb part 3 side is illustrated, it is similarly made difficult for the scooped-up hair bundle to slide down by the first recessed parts 3 h and the first comb tooth recessed parts 6 h when the scooping-up task is performed on the front side of the comb 1. The same can be said even when the scooping-up task is performed by either the front side or the back side of the comb 1 on the other-end edge comb part 4 side.

FIG. 9 illustrates a situation of a task where the comb 1 is inserted into the hair, and the one-end edge comb part 3 is moved in order to divide the hair into a hair bundle h1 and a hair bundle h2 by the one-end edge comb part 3 (for parting, etc.). In this case, the tip end 3 v of the one-end edge comb part 3 is made in a state where it abuts on the scalp T, the comb 1 including the one-end edge comb part 3 is moved in the X-axis direction, and the hair is sequentially divided into the hair bundle h1 and the hair bundle h2 by the one-end edge comb part 3.

Here, in the one perimeter edge 3 f of the one-end edge comb part 3, since the tip end through-hole 8 having the counter bore 8 a is opened in the tip-end side 3 a, and the first recessed part 3 h is formed in the middle part 3 c, the one hair bundle h1 divided by the one perimeter edge 3 f does not contact the one-end edge comb part 3 in the parts where the counter bore 8 a, the tip end through-hole 8, and the first recessed part 3 h are located but contacts the perimeter edge 3 f in the part other than these parts. Therefore, compared with the conventional combs where the tip end through-hole 8, the counter bore 8 a, and the first recessed part 3 h do not exist, the one-end edge comb part 3 according to the first embodiment is decreased largely in the contacting range (contacting area) with the hair bundle h1, and thereby, the contact resistance by the hair bundle h1 to be divided decreases, and the one-end edge comb part 3 becomes easy to smoothly move inside the hair.

The same can be said for the other perimeter edge 3 g of the one-end edge comb part 3, and the contacting range (contacting area) of the hair bundle h2 decreases, due to by the tip end through-hole 8 having the counter bore 8 a on the tip-end side 3 a, and the second recessed part 3 i in the middle part 3 c. Thus the contact resistance with the hair bundle h2 also decreases in connection therewith, and thereby, it becomes easy for the one-end edge comb part 3 to move in the hair, and the operability and workability of the comb 1 improve.

Note that, the comb 1 according to the first embodiment is not limited to the form described above, but various modifications may be considered. For example, if the task where the one-end edge comb part 3 etc. as illustrated in FIG. 9 is inserting into the hair and move the comb 1 etc. is not considered, it is possible to omit the formation of the tip end through-hole 8 of the one-end edge comb part 3 or the tip end through-hole 9 of the other-end edge comb part 4.

FIG. 10 is a front view of the comb 1, and illustrates one example where the range of the plurality of comb teeth 6 surrounded by the one-end edge comb part 3 and the other-end edge comb part 4 is divided into ranges different from the first range 1 a and the second range 1 b which are illustrated in FIG. 1 so that it is divided into one end range 1 c close to the one-end edge comb part 3, a central range 1 d corresponding to the central part 2 e of the comb main body 2, and the other end range 1 e closed to the other-end edge comb part 4. Although in the example described above the first comb tooth recessed parts 6 h or the second comb tooth recessed parts 6 i are formed in the comb teeth 6 of the entire range, it is possible, as one modification, to omit the formation of one or both of the first comb tooth recessed parts 6 h and the second comb tooth recessed parts 6 i in the comb teeth 6 included in the central part 2 e. This corresponds to that the central part 2 e can secure a user-friendliness similar to the conventional combs.

On the other hand, when the side where the comb 1 is gripped is limited to the other-end edge comb part 4 side, when the one-end edge comb part 3 requires similar user-friendliness of the comb to the conventional arts, or the like, it may be considered to omit the formation one or both of the first comb tooth recessed parts 6 h and the second comb tooth recessed parts 6 i of the comb teeth 6 included in the one end range 1 c, and further omit the formation of one or both of the first comb tooth recessed parts 6 h and the second comb tooth recessed parts 6 i in the comb teeth 6 included in the one end range 1 c and the central range 1 d.

Similarly, when the side where the comb 1 is gripped is limited to the one-end edge comb part 3 side, or when the other-end edge comb part 4 requires similar user-friendliness of the comb to the conventional arts, or the like, it may be considered to omit the formation of one or both of the first comb tooth recessed parts 6 h and the second comb tooth recessed parts 6 i of the comb teeth 6 included in the other end range 1 e, and further omit the formation of one or both of the first comb tooth recessed parts 6 h and the second comb tooth recessed parts 6 i of the comb teeth 6 included in the other end range 1 e and the central range 1 d.

Moreover, as illustrated in FIGS. 7(a) and (b), when supporting the comb 1 at the comb teeth 6 without touching the one-end edge comb part 3 and the other-end edge comb part 4 etc. as the main purpose, it may be considered to omit the formation of one or both of the first recessed parts 3 h and the second recessed parts 3 i in the one-end edge comb part 3, and similarly in the other-end edge comb part 4, it may be considered to omit the formation of one or both of the first recessed parts 4 h and the second recessed parts 4 i (the first recessed parts 3 h and 4 h and the second recessed parts 3 i and 4 i of the one-end edge comb part 3 and the other-end edge comb part 4 are omissible. The one end depressed part 3 e and the other-end depressed part 4 e of the one-end edge comb part 3 and the other-end edge comb part 4 are also omissible).

Further, it can also be considered that, in association with the omission of the first comb tooth recessed parts 6 h and the second comb tooth recessed parts 6 i of the comb teeth 6 included in the one end range 1 c, or the one end range 1 c and the central range 1 d, which are described above, the formation of one or both of the first recessed parts 3 h and the second recessed parts 3 i in the one-end edge comb part 3 is omissible (note that the formation of the one-end depressed parts 3 e is also omissible). Further, it may be considered that, in association with the omission of the formation of one or both of the first comb tooth recessed parts 6 h and the second comb tooth recessed parts 6 i of the comb teeth 6 included in the other end range 1 e, or the unconcerned range 1 e and the central range 1 d, which are described above, the formation of one or both of the first recessed parts 4 h and the second recessed part 4 i in the other-end edge comb part 4 is omitted (note that the formation of the other end depressed part 4 e is also omissible).

Moreover, although in the example described above the radius of curvature R2 centering on the deepest part of the first comb tooth recessed part 6 h and the second comb tooth recessed part 6 i of the comb teeth 6 in the entire range is the same, it is also possible to change the radius of curvature R2 according to the position where each of the comb teeth 6 is formed.

For example, as for the comb teeth 6 located in a part close to the one-end edge comb part 3, the dimension of the radius of curvature R2 of the first comb tooth recessed part 6 h and the second comb tooth recessed part 6 i is made same as the radius of curvature R1 of the first recessed part 3 h and the second recessed part 3 i of the one-end edge comb part 3; however, it may be considered that the dimension of the radius of curvature R2 is made gradually smaller as approaching to the central range 1 d in the one end range 1 c illustrated in FIG. 10 so that the radius of curvature R2 is “0” in the central range 1 d, i.e., the first comb tooth recessed parts 6 h and the second comb tooth recessed parts 6 i are not formed, the radius of curvature R2 is generated in the other end range 1 e, the radius of curvature R2 increases as approaching to the other-end edge comb part 4, and the dimension of the radius of curvature R2 is again made same as the dimension of the radius of curvature R1 in the part close to the other-end edge comb part 4, etc.

By doing so, the depth of the first comb tooth recessed parts 6 h and the second comb tooth recessed parts 6 i of the respective comb teeth 6 becomes gradually shallower from the deep state as it goes from the one end side 2 a of the comb main body 2 to the other end side 2 b via the central part 2 e. Here, although the comb tooth recessed parts are once disappeared in the central range 1 d, the comb tooth recessed parts are again generated and the depth increases so that the depth gradually changes, and thereby, the fitting condition of the fingers becomes appropriate without causing any step etc. in the space formed by the comb tooth recessed parts of the respective comb teeth 6.

Note that, as the ratio of the one end range 1 c, the central range 1 d, and the other end range 1 e, which are illustrated in FIG. 10, if the entire range of the plurality of comb teeth 6 is assumed to be “1,” the ranges 1 c-1 e are equalized to make each ratio to be “1/3,” or the ranges 1 c-1 e are made unequal so that, for example, the one end range 1 c and the other end range 1 e are made to be “2/5” and the central range 1 d is made to be “1/5.” The ratios of these ranges 1 c-1 e may suitably be set according to the specification, purpose, etc. of the comb 1.

FIGS. 11(a) and (b) each illustrates another modification, where FIG. 11(a) illustrates one-end edge comb part 13 of the modification, and although a first curve-shaped recessed part 13 h is formed in the middle part 13 c of the one perimeter edge 13 f in the width direction (Z-axis direction), the middle part 13 c of the other perimeter edge 13 g is connected with the tip-end side 13 a and the root side 13 b by flat surfaces, similar to the conventional combs, without forming the second recessed part. Such one-end edge comb part 13 of this modification becomes a suitable modification when a similar user-friendliness of the other perimeter edge 13 g to the conventional combs is required in a case where the gripping by the user's finger (e.g., thumb) is considered to be caused only at the one perimeter edge 13 f side (when the index finger is allowed to grip normally), a case where the task to scoop up the hair bundle is limited to the one perimeter edge 13 f side, or the like. Note that, the modification according to FIG. 11(a) is similarly applicable to the other-end edge comb part.

FIG. 11(b) illustrates a comb tooth 16 of one modification, and the comb tooth 16 of this modification is combined with the one-end edge comb part 13 of the modification described above, where, similar to the one-end edge comb part 13 illustrated in FIG. 11(a), although a first comb tooth recessed part 16 h is formed in the middle part 16 c of one perimeter edge 16 f in the width direction (Z-axis direction), the other perimeter edge 16 g has the middle part 16 c connected with the tip-end side 13 a and the root side 13 b by flat surfaces, similar to the conventional combs. Such a comb tooth 16 of this modification becomes a suitable modification when a similar user-friendliness of the other perimeter edge 16 g to the conventional combs is required in a case where the gripping by the user's finger (e.g., thumb) is considered to be caused only at the one perimeter edge 16 f side (when the index finger is allowed to grip normally), a case where the task to scoop up the hair bundle is limited to the one perimeter edge 16 f side, or the like.

Note that, although FIGS. 11(a) and (b) described above illustrate the cases where the first recessed part 13 h and the first comb tooth recessed part 16 h are formed in the one perimeter edge 13 f of the one-end edge comb part 13 and the one perimeter edge 16 f of the comb tooth 16, respectively, it is also possible, of course, by replacing the right and left sides, to form the second recessed part and the second comb tooth recessed part in the other perimeter edge 13 g of the one-end edge comb part 13 and the other perimeter edge 16 g of the comb tooth 16, respectively. Moreover, each modification according to FIGS. 11(a) and (b) may also be combined with each modification described based on FIG. 10 described above.

FIGS. 12(a) and (b) each illustrates another modification, and one-end edge comb part 23 according to this modification of FIG. 12(a) has a feature in that sharp edges 23 r and 23 s which are corners are formed in parts where first and second recessed parts 23 h and 23 i formed in both perimeter edges 23 f and 23 g of a middle part 23 c are connected with a root side 23 b, respectively. In order to form such edges 23 r and 23 s, the first and second recessed parts 23 h and 23 i are structured such that points of inflection are not provided in the part close to the root side 23 b, but curves (curved surfaces) which are convex in ranges located nearby are directly connected with the flat-like perimeter edges 23 f and 23 g on the root side 23 b, centering on the deepest parts. If such edges 23 r and 23 s are formed, as just illustrated in FIG. 6(a), when the user's finger (e.g., thumb) is fitted into either one of the first and second recessed parts 23 h and 23 i, one of these edges 23 r and 23 s is caught by the user's finger, thereby further increasing gripping power and further improving the antiskid function. Note that, the modification according to FIG. 12(a) is similarly applicable to the other-end edge comb part.

FIG. 12(b) illustrates a comb tooth 26 of one modification, and similar to the one-end edge comb part 23 of the modification illustrated in FIG. 12(a), the comb tooth 26 of this modification also has a feature in that sharp edges 26 r and 26 s which are corners are formed in parts where first and second comb tooth recessed parts 26 h and 26 i formed in both perimeter edges 26 f and 26 g of a middle part 26 c is connected with a root side 26 b. Also in the comb tooth 26 of such a modification, these edges 26 r and 26 s each increases the gripping power of the user's finger, and further improves the antiskid function in the comb tooth. Note that, the modification illustrated in FIG. 12(a) may be used solely, without combining with the modification illustrated in FIG. 12(b), and similarly, the modification illustrated in FIG. 12(b) may also be used solely, and if it is used solely in this way, the gripping power can be increased partially.

Moreover, although in FIGS. 12(a) and (b) described above, the edges 23 r and 23 s, and the edges 26 r and 26 s are formed in both the perimeter edges 23 f and 23 g of the one-end edge comb part 23, and both the perimeter edges 26 f and 26 g of the comb tooth 26, it is also possible, of course, to form the edge(s) only in one of the perimeter edges. Moreover, each modification according to FIGS. 12(a) and (b) may also be combined with each modification according to FIG. 10 or FIG. 11(a) and (b) described above.

FIGS. 13(a) and (b) each illustrates another modification, and one-end edge comb part 33 according to the modification of FIG. 13(a) has a feature in that sharp edges 33 t and 33 u which are corners are formed in parts where first and second recessed parts 33 h and 33 i formed in both perimeter edges 33 f and 33 g of a middle part 33 c is connected with a tip-end side 33 a. In order to form such edges 33 r and 33 s, the first and second recessed parts 33 h and 33 i are structured such that points of inflection are not provided in parts close to a tip-end side 33 a, but centering the deepest parts, curves (curved surfaces) which are convex within ranges nearby are directly connected with the perimeter edges 33 f and 33 g on the tip-end side 33 a. If such edges 33 t and 33 u are formed, as just illustrated in FIG. 8(b), when the scooped-up hair bundle h is fitted into either one of the first and second recessed parts 33 h and 33 i, these edges 33 t and 33 u are caught by the scooped-up hair bundle h, and the possibility of the scooped-up hair bundle h sliding down from the one-end edge comb part 33 can further be reduced. Note that, the modification according to FIG. 13(a) is similarly applicable to the other-end edge comb part.

FIG. 13(b) illustrates a comb tooth 36 of one modification, and similar to the one-end edge comb part 33 of the modification illustrated in FIG. 13(a), the comb tooth 36 of this modification has a feature in that sharp edges 36 t and 36 u which are corners are formed in parts where first and second comb tooth recessed parts 36 h and 36 i formed in both perimeter edges 36 f and 36 g of a middle part 36 c are connected with a tip-end side 36 a. Also in the comb teeth 36 of such a modification, the possibility of the scooped-up hair bundle h (see FIG. 8(c)) sliding down from the comb teeth 36 is further reduced by these edges 36 t and 36 u. Note that, the modification illustrated in FIG. 13(a) may be used solely, without combining with the modification illustrated in FIG. 13(b), and similarly, the modification illustrated in FIG. 13(b) may also be used solely, and if it is used solely in this way, it is useful for further reducing the possibility of the scooped-up hair bundle sliding down.

Moreover, although in FIGS. 13(a) and (b) described above, the edges 33 t and 33 u, and the edges 36 t and 36 u are formed in both the perimeter edges 33 f and 33 g of the one-end edge comb part 33, and both the perimeter edges 36 f and 36 g of the comb tooth 36, it is also possible, of course, to form the edge(s) only in one of the perimeter edges. Moreover, each modification according to FIGS. 13(a) and (b) may also be combined with each modification according to FIG. 10 or FIGS. 11(a) and (b) described above.

FIGS. 14(a) and (b) each illustrates another modification, and one-end edge comb part 43 according to the modification of FIG. 14(a) is such that the structure according to the edges 23 r and 23 s of the one-end edge comb part 23 according to the modification of FIG. 12(a), and the structure according to the edges 33 t and 33 u of the one-end edge comb part 33 according to the modification of FIG. 13(a) are combined. That is, one-end edge comb 43 has a feature in that edges 43 r and 43 s are formed in parts where a first and second recessed parts 43 h and 43 i formed in both perimeter edges 43 f and 43 g of a middle part 43 c is connected with a root side 43 b, and in that edges 43 t and 43 u are formed in parts where the first and second recessed parts 43 h and 43 i are connected with a tip side 43 a. The one-end edge comb part 43 can exhibit the antiskid function by the edges 43 r and 43 s on the root side 43 b, and the sliding-down of the scooped-up hair bundle is reduced by the edges 43 t and 43 u on the tip-end side 43 a. Note that, the modification according to FIG. 14(a) is similarly applicable to the other-end edge comb part.

FIG. 14(b) illustrates a comb tooth 46 of one modification, and the comb tooth 46 of this modification is also a combination of the structure according to the edges 26 r and 26 s of the comb tooth 26 according to the modification of FIG. 12(b), and the structure according to the edges 36 t and 36 u of the comb tooth 36 according to the modification of FIG. 13(b). That is, edges 46 r and 46 s are formed in parts where first and second comb tooth recessed parts 46 h and 46 i formed in both perimeter edges 46 f and 46 g of a middle part 46 c is connected with a root side 46 b, and edges 46 t and 46 u are formed in parts where first and second comb tooth recessed parts 46 h and 46 i are connected with a tip-end side 46 a. The comb tooth 46 can exhibit the antiskid function by the edges 46 r and 46 s on the root side 46 b, and can reduce the sliding-down of the scooped-up hair bundle by the edges 46 t and 46 u on the tip-end side 46 a. Note that, the modification illustrated in FIG. 14(a) may be used solely without combining with the modification illustrated in FIG. 14(b), and similarly, the modification illustrated in FIG. 14(b) may also be used solely.

Moreover, although in FIGS. 14(a) and (b) described above the edges 43 r-43 u and the edges 46 r-46 u are formed in both the perimeter edges 43 f and 43 g of the one-end edge comb part 43 and both the perimeter edges 46 f and 46 g of the comb tooth 46, it is also possible, of course, to form the edge(s) only in one of the perimeter edges. Moreover, each modification according to FIGS. 14(a) and (b) may also be combined with each modification according to FIG. 10 or FIGS. 11(a) and (b) described above.

Example 2

FIG. 15(a) is a front view schematically illustrating an entire comb 50 according to a second embodiment of the present disclosure. The comb 50 according to the second embodiment has a structure so that a bar-like grip part 51 projects from the other-end edge comb part 54. Also in the comb 50 of a type having such a grip part 51, similar to the first embodiment, first recessed parts 53 h and 54 h are formed in middle parts of one perimeter edges of one-end edge comb part 53 provided to one end side 52 a of a comb main body 52, and the other-end edge comb part 54 provided to the other end side 52 b of the comb main body 52, respectively, and second recessed parts are formed in middle parts of the other perimeter edges, and also in a plurality of comb teeth 56 surrounded by these one-end edge comb part 53 and the other-end edge comb part 54, first and second comb tooth recessed parts are formed in both perimeter edges, respectively. Note that, in the comb 50, a tip end through-hole 58 is formed in a tip-end side of the one-end edge comb part 53, and a tip end through-hole 59 is formed on a tip-end side of the other-end edge comb part 54.

Thus, although the bar-like grip part 51 projects, since the comb 50 according to the second embodiment has fundamentally a similar structure to the first embodiment, even if the comb is used by the way to grip the comb centering on the one-end edge comb part 53, the antiskid function can be exhibited by a first recessed part etc. of the one-end edge comb part 53, and first comb tooth recessed parts etc. formed in the respective comb teeth 56 near the one-end edge comb part 53, and the sliding-down of the scooped-up hair bundle can be reduced, and even if the comb is used by the way to grip the comb centering on the other-end edge comb part 54, the antiskid function can be exhibited also at this side and the sliding-down of the scooped-up hair bundle can be reduced by a first recessed etc. part of the other-end edge comb part 54, and first comb tooth recessed parts etc. formed in the respective comb teeth 56 near the other-end edge comb part 54. Note that, also in the comb 50, according to the second embodiment, the various modifications described in the first embodiment may also be applicable.

FIG. 15(b) is a front view illustrating an outline of a comb 60 of one modification according to the second embodiment. The comb 60 according to this modification is structured so that a grip part 65, which is not the bar-like but plate-like, projects from the other-end edge comb part 64. Thus, even when the plate-like grip part 65 projects, the comb 60 maintains a similar structure to the first embodiment. That is, in the comb 60, first recessed parts 63 h and 64 h are formed in middle parts of one perimeter edges of one-end edge comb part 63 provided to one end side 62 a of a comb main body 62, and the other-end edge comb part 64 provided to the other end side 62 b of the comb main body 62, and second recessed parts are formed in middle parts of the other perimeter edges, and first and second comb tooth recessed parts are formed in both perimeter edges also in a plurality of comb teeth 66 surrounded by the one-end edge comb part 63 and the other-end edge comb part 64, respectively. Note that, in the comb 60, a tip end through-hole 69 is formed in a tip-end side of the other-end edge comb part 64, and a tip end through-hole 68 is formed in a tip-end side of the one-end edge comb part 63. Note that, also in the comb 60 according to this modification, the various modifications described in the first embodiment may also be applicable.

INDUSTRIAL APPLICABILITY

The present disclosure can suitably be used for reducing the load on the fingers which grip the comb, increasing the gripping power, and preventing the hair bundle scooped up by the comb from sliding down from the comb.
